Ain Tsila is a gas condensate field situated in the Illizi Basin, Algeria, located within the Isarene permit in Blocks 228 and 229a. The Ain Tsila field boasts reserves amounting to 2.1 trillion cubic feet of sales gas, alongside 67 million barrels of condensate and 108 million barrels of liquefied petroleum gas (LPG). Discovered in 2009 through the successful drilling of the Ain Tsila-1 well, this gas condensate field garnered significant recognition, ranking as the ninth-largest discovery globally for that year. Spanning an extensive area exceeding 1,000 square kilometers, Ain Tsila represents a substantial addition to the energy landscape.

The Berri field, situated along the eastern coast of Saudi Arabia, is undergoing expansion through the Berri Increment Program (BIP) to increase its crude production capacity to 500,000 barrels per day (bpd). Initially discovered in 1964, the Berri field commenced crude oil production in 1970, with the Berri gas plant starting operations in 1977. Currently capable of producing 250,000 bpd of Arab Light crude, the field’s expansion program aims to double its crude production capacity through enhanced oil recovery techniques.
